National Instruments Direct Injector Driver System Manual

DIX_BackBoostTime

Tip Strip: Time period during which injector solenoid energy is directed back to the module boost power

supply (after end of pulse)

Units: msec

Detail: The time period at the end of the injection pulse for which the back-electromotive force (EMF) of the

injector solenoid is directed to the internal boost power supply.

IPhaseArray

When operating solenoid injectors, the

IPhaseArray

defines up to eight sequential current-drive phases

within each injection command. Each phase is implemented sequentially and can specify

upper

and

lower

current dithering setpoints,

phase duration

, and

drive circuit – high voltage or battery voltage

. The high

voltage drive circuit should only be used as little as necessary so that the internal boost power supply

energy is conserved and not overloaded. Please refer to the

DI Driver Rev F

manual for various

IPhaseArray

configurations and the resulting current profile of the Solenoid injector. The

IPhaseArray

consists of the

following parameters:

IPhaseDrive

Tip Strip: Selects low voltage or high voltage for the associated phase

Detail: When operating solenoid injectors, selecting these buttons will toggle the voltage drive source

of the associated phase between

high voltage (HV)

and

battery voltage (LV)

IPhaseArray

is used differently in piezo mode by enabling

DIX_PiezoEnable

. The eight elements of

the

IPhaseArray

are divided into two groups. The first four elements are used for charging the piezo

load at the beginning of injection, and the last four elements are used for discharging the piezo load

at the end of injection. The ability to select HV or LV for each phase is not available for piezo injector

operation because the high voltage driver circuit is always used (as shown below).

IPhaseCurrentUpper

Tip Strip: Upper current dithering setpoint

Units: Amps

Detail: Upper threshold for current dithering set-point in Amps.
